PORTSMOUTH — The Portsmouth woman charged with lying to police about her whereabouts on the night UNH student Elizabeth Marriott was allegedly murdered waived her probable cause hearing this morning.

The attorney representing Kathryn “Kat” McDonough called the 19-year-old "young and impressionable" during a brief hearing in Portsmouth Circuit Court. He said the investigation has been "frightening" for McDonough, who is aware of her legal responsibilities.

McDonough has been out on bail since Sunday after being arrested last week on charges connected with the disappearance and presumed killing of Marriott. She was taken into custody on Dec. 24 at Michaels craft store in Newington, her place of employment.

McDonough is charged with one felony count of hindering apprehension or prosecution and one felony count of conspiracy to do the same. She faces up to seven years in prison on either charge.

McDonough appeared in court Wednesday wearing glasses, a pink blouse and a black pencil skirt. She was ordered to have no contact with the Marriott family or Mazzaglia while she awaits trial.
